Electrical Hook-Up - Midas Mida.Black 8 Installation Instructions Manual

1.9 Electrical hook-up

Important— Although the heat pump is electrically isolated from the rest of the unit, this only prevents
the passage of electricity to or from the pool water. Grounding the unit is still required to protect
yourself from short circuits inside the unit. Make for adequate ground connection.
Check if the electrical mains voltage corresponds with the operating voltage of the heat pump prior to
hooking up the unit.
It is recommended to use a separate fuse(slow type-D-curve)as well as adequate wiring(see table below).
For horizontal models : remove the panel on the right of the fan opening.
For vertical models: remove the curve panel in the front side.
Connect the electrical wires with the terminal block labelled
Next to this connection, there is a second terminal block labelled
pump (max.5A/240V)can be connected. This is connection makes it possible to control filter pump
operation with the heat pump. See further at Parameter setting table (Parameter 9) for the different
possibilities.

Remarks — for models with 3 phases, switching 2 phases may cause in inversion in the rotational direction
of electrical motors, which could damage the unit. Therefore, a protection device has been built in, which
will interrupt the circuit if the connection has not been performed correctly.
